Here is a digital alarm clock made using PIC 18F4520 Microcontroller and DS3234 RTC (Real Time Clock). This project is for educational purposes or can be used as a reference for integrating DS3234 RTC. DS3234 is a very accurate RTC IC with integrated on chip temperature compensated crystal oscillator. It can be integrated with a microcontroller using SPI bus. This project is developed using MPLAB XC8 compiler.

In order to send e-mail from ESP8266 Module, we need to use the SMTP protocol. Hence, an SMTP Server is required to send the e-mails and the ESP8266 will act as an...

In this project we will control an LED which is connected to ESP8266 with a Telegram bot. Hope you know about Telegram, it is a messenger app similar to Whatsapp. This enables users to control their ESP8266 via simply typing and sending commands in Telegram. By adding some relays or TRIAC you can make this a home automation project.

In this article, I am going to explain about interfacing of DHT11 sensor with ESP8266. For that we have to make only 3 connections between the DHT11 sensor and ESP8266. For the working demonstration we will be programing ESP8266 as a web server for displaying temperature and humidity in a web browser as per request.

In this project, we are going to log and monitor temperature data over internet using ThingSpeak IoT server. And we can view the logged data and graph over time in their website. It is made using ESP8266 WiFi module and LM35 temperature sensor. ESP8266 WiFi chip reads the current temperature from LM35 using ADC and sends it to ThingSpeak server for live monitoring from anywhere in the world.
